Individual-differences multidimensional scaling analysis of

neural and cognitive representations

Analyses of the neural systems involved in behavioral and cognitive tasks are typically constrained by (1) prior assumptions of variables of interest, (2) limits on task complexity, and (3) difficulties in reconciling the heterogeneity of individual responses. I will describe an approach to discovering the structure of neural and cognitive representations that derives dimensions of interest in a model-neutral fashion and represents individual variability as a population of vectors in an abstract space. I have tested this approach on three data sets: (1) single-unit neural data from a three-dimensional spatial task, (2) behavioral data from a visual construction judgment, and (3) neural and behavioral data from a tactile attention task.
